Using the equation 2h2+o2--> 2h2o, if 192g of oxygen are produced, how many grams of hydrogen must react with it

The balanced chemical reaction is:

2H2+O2-->2H2O

To determine the mass of hydrogen that is needed, we need use the initial amount of oxygen and relate it to hydrogen from the reaction given. We do as follows:

192 g O2 ( 1 mol O2 / 32 g O2) ( 2 mol H2 / 1 mol O2 ) ( 2.02 g H2 / 1 mol H2 ) = 24.24 g H2

The answer is c if i’m not wrong
